Then your device probably doesn't have the FW bug.

Seeing the warning message in this case is not a bug. It tells you that having
conservation mode and rapid charge enabled at the same time is out of spec.
Writing 1 to conservation_mode clears the rapid charge bit. As long as the
warning doesn't appear again after tuning charge_types or conservation_mode,
you can safely forget it.
